The State of California's Title 24 Building Energy Efficiency Standards have long provided national leadership in improving building energy efficiency. First introduced in the 2005 Title 24 and expanded for 2008, Acceptance Testing is one of the core components of the Standards' ongoing effort to optimize energy use in modern construction. It's intent is to address the importance of proper system installation, as realized energy savings from advanced systems depend on them being installed and operating properly.

This design brief summarizes the purpose and structure of Acceptance Testing, outlining current requirements and terminology, highlighting benefits, and recommending strategies to optimize its effectiveness in a practical manner. This design brief is intended as a high-level overview of the Acceptance Testing process, and we strongly encourage readers to review the compliance manual and other documents referenced in this design guide for detailed test procedures.
